Hello, have been working on a civic that was sitting for a while. Had it towed to a shop, they gave it a new battery and did some minor maintenance, was able to drive it home. Car wouldn't start a few weeks later, was turning over but would stall out. Changed the spark plugs, nothing. Got OBD code said EVAP purge valve was malfunctioning, replaced it and it started right up. Drove it around for about 2 days then won't start again like before. Car has battery life, and turns but stalls out quickly. Not getting anymore OBD codes.

Any suggestions?

Check battery and ground connections, check that everything is plugged in

and fuses?

SOLVED

I found the problem: immobilizer was causing shutoff due to rejecting 2 of my 3 keys. FYI if you see green key light blinking for more than a few seconds after turning key to ON(II) position it means there is an issue with the immobilizer. In this case 2 of my keys are bad, not the lock.
